Girl you might ask for date? (8)
I believe the answer is:
calendar
'for date?' is the definition.
(I've seen this before)
'girl you might ask' is the wordplay.
I cannot quite see how this works, but
'girl' could be 'cal' and 'cal' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for calendar that I've seen before include "that's stuffed with dates" , "Tabular array of days" , "List of days etc" , "Chart of times" , "Diary" .)
